I think this is an excellent point, but I'll add that we don't have the economies of scale for it either. If there was enough demand for a tourbillon, an Apple-esque company would emerge (maybe Richemont or Patek) and drive the costs down for manufacturing. Other than that, part of the appeal is the handcraftsmanship involved in these pieces.
